JOHN CHRISTOPHER NIOHOL, OF MONTREAL, QUEBEC, CANADA, ASSIGNOR OF ONE-THIRD TO WILLIAM JOI-IN PATERSON, OF TORONTO, CANADA.

CdR-AXLE LUBRICATOR.

Specification of Letters Patent.

Application led January 18, 1908.

To all whom it may con/cern:

Be it knoivn that I JOHN Onaisrornnn Niel-IOL, of the city oi ontreal, l rovince of Quebec, Canada, have invented certain neu'Y and useful Improvements in Car-Axle liubricators, and l do herehy declare that the following is a iull, clear, and exact description oi the saine.

lily invention relates to the type of car lil axle luhricators for applying the lubricant hy capillary action and it has for its object to provide a luforicator '\i".ich can oe readily introduced into and removed troni the axle boxes at present in use, and one which will 13 maintain its proper Working position ,vithout special construction oi' the axle hex or the use of adjusting devices.

The invention inay he said hrieiiy to consist of the combination ci parts hereinafter described and pointed out in the clairns.

For full comprehension, however ci iny invention reference inust 1oe had to the ad coinpanying drawings forniing a part oi this specification, in which snnilar reierence chan' s actors indicato the saine parts, and wherein- Figure l is a longitudinal. vertical sectional vieuT oi an axle hex, with the axle end and niy in'iproved luhrlcator sliozrn therein in eleva-tion, Fig. 2 is a plan vies. oi the l'uhri- :nl cator; and Fig. 8 is a longitudinal vertical sectional view thereof taken on line is A, Fig. 2. Fig. el is a detail transverse sectional vien'v oi one leg of the fulcruin iranie illustrating particularly one of the devices for preventing displacement of such traine on the hase.

Speciiically speaking the hase referahly consists of an open frame rectangu ar in plan viev: and hai/'ing its sides curved upwardly as at l) and presenting a pair of vertical stops c and a pair oi notches (l, such hase 1seing intended. for permanent location in the axle box and its dimensions, in plan, are such that it lits snugly the lines olf' juncture or" the 5 sides f and ends g of the 1sox with the flat bottoni 7L thereof. A removable iulcruin frame rests on this hase and it is preferably of U-'l'orin and presents a pair of inwardly extending, trunnions le and outv-fardly extending lugs mV oi polygonal cross section at the ends oi its legs, While a pair oi locking devices fn, o, extend outwardly and dov-,fn- Wardly from such legs near the opposite ends thereof. The lugs m i'it tightly against the 55 bases of the stops c, the vertical portions 'n ol the locking devices n, o project into and engage the rear Walls oi the notches d, and the horizontal portions o of such devices a, o rest upon the top of the sides of the 1oase, when the parts are in operative position. This traine presents an upwardly curved portion y" to serve as a means whereby it, and the shoe kwith the felt' can he withdrawn troni the axle-box independently of the hase. l gravity' ineinher is pivoted upon this removable traine and consists preferably an open traine, ci substantially rectanguiar forni, presenting Weighted feet r, a cross 1par s, and a pair oi hearings t lieta/een its ends, such hearings being rotatably iastened upon the trunnions 7c, and the cross har s has a pair of stops a cast thereon. This 0ravity ineniher supports and coacts sith a tilting shoe w carrying the telt :c or other niediuin through which the lubricant is conducted to the axle hy capillary action.

The tilting shoe is preferably ci reotangular forni in plan view and curved transversely concentrically to the axle, the underside thereof being reinforced at its ends ley transverse ribs fg/ vhile the loody thereof is 'loi-ined udth transverse slots e through Winch the felt is passed, one or both ends ol the latter being slit as at 2 and trailing in the lubricant in the bottoni ol the box. The dimensions ci the hase heing commensurate with the bottoni of the loox localize the operating parts a sui'iicient distance troni the sides and ends thereof to eiiectively prevent the `v-feighted feet or shoesin their operation striking or 1seing interfered with by any part ci the interior oi the box.

Operation: The Weighted feet r are norinally supported lree of the floor oi the box hy the depression of the shoe as it hears upon the underside o1" the axle, and they thus cause the felt carried by the shoe w to hear yieldingly upon the axle and apply thereto the lubricant picked up hy capillary action, and caring to the curvature of the shoe and the pivotal relation between the saine and the gravity traine and the base, such shoe will automatically adapt itseli to any variations, horizontal, vertical or diagonal, in the angular position ci the axle relatively to the axle hex, while the ivorling parts can he readily removed troni the hase in the box in their entirety for inspection or cleansin@i or the renewal of the felt, and returned to p ace at Will.

ICO

vJ'Vhat claim is es follows l. The combination with an axle-box, of a lubrieetor comprising e base, a removable member supported by the bese, a rocker frame fulcrumed upon the removable member and having one end ,veighted, and a, shoe pivotally secured to the opposite end of the rocker frame.

2. The combination with en axle-box, ol2 e lubricetor comprising e bese resting upon the bottom of the box and consisting of an open rectangular frame having its sides curved upwardly and presenting stops and notches, a member removably supported by the bese and presenting lugs adapted to engage the stops and devices adapted to engage the notches, a pair of trunnions upon such member; e rocker frame fulerunied upon the trunnions and having one end Weighted and @transverse ber carried by the opposite end thereof; and e shoe pivotelly secured to the transverse bar of the rocker frame enel -e-depted to carry u lubricant conveylng medium. Y

in testimony whereof, l have signed my neme to this specification, in the presence of tivo subscribing vwitnesses.
